    Surgical margins for resection of squamous cell carcinoma of the lower lip

    No full text
    A prospective studs was undertaken to evaluate the efficacy of 3 mm margins of resection with surgical excision of squamous cell carcinoma of the lower lip (SCCLL) in its earls stages hereby the margins were checked with the systematic use of frozen-section examination. During the period of 1991-1998. 72 consecutive patients with a primary stage I/II SCCLL underwent surgical excision as the initial treatment. There were 58 males (81%) and 14 females (19%) with a median age of 66.8 years (range 37-91 years), The majority of cases (94.4%) were stage I tumours. Treatment consisted of a full-thickness excision including a 3 mm margin of clinically uninvolved tissue. Intraoperative frozen-section analysis of the margins of the excised specimen was used to confirm tumour-free margins. Clinically determined margins were tumour-free in 89.9% on initial excision. The false-positive rate associated with frozen-section analysis was 1.4%. The mimumum follow-up period for all patients was 2 years (median 5.1 years. range 2-9 years). Local recurrence was found in two patients A 3 mm margin with excision of early SCCLL seems to be appropriate. if the margins are controlled by systematic use of frozen-section analysis

    Recently, the Dutch National Immunization Programme has started to offer the human papillomavirus (HPV) vaccination to boys as well as girls from the age of 10. The vaccine protects against long-term HPV infection, which can lead to cervical, anogenital and oropharyngeal cancer. Besides malignant disorders, a HPV infection can also lead to certain disorders of the skin and oral cavity. Since the national HPV vaccination campaign has probably resulted in more awareness among patients about the relation between HPV and oropharyngeal cancer, patients may consult oral healthcare professionals with questions about HPV infection. Oral healthcare professionals are thus able to play a role in preventing HPV related disorders by counseling their patients on HPV. They can also contribute to early diagnosis of HPV related oral and oropharyngeal disorder, although the possibility of detecting oropharyngeal cancer during routine dental examination is limited

    Intralesional infiltration of corticosteroids in the treatment of localised langerhans cell histiocytosis of the mandible report of known cases and three new cases

    Langerhans' cell histiocytosis (LCH) can involve virtually any site and organ of the body, either as an isolated lesion or as a widespread systemic disease. Bone can be involved as a part of generalised disease or as a separate entity, formerly known as eosinophilic granuloma. The clinical cause of localised LCH (LLCH) to bone is generally benign. Solitary bone lesions may resolve spontaneously after diagnostic biopsy in a period of months to years. If treatment is indicated, as in larger lesions with pain, swelling and risk for spontanous fracture, the disease can be controlled, by chemotherapy or local measures such as surgical curettage, low-dose radiotherapy and intralesional injection of corticosteroids. There are no controlled studies in the literature comparing outcomes of these treatment modalities because of low incidence of the disease and general tendency to regress. Three patients (female, 28 months; male, 9 years; male, 15 years) with LLCH of the mandible were treated in an one stage procedure with intralesional injection of 80, 40 and 80 mg methylpredisolone succinate, respectively, as the primary form of treatment. Patients were seen for clinical and radiological evolution 1, 3, 6, 9 and 12 months after treatment, and yearly thereafter. The overall outcome was excellent. The lesions showed clinically and radiologically complete remission approximately 6 months after treatment. There were no complications nor morbidity of the treatment. After a follow-up period of 12 months, the patients are well with no evidence of residual disease on radiographs. Local injection of corticosteroids should be the initial choice of treatment of LLCH of the mandible, because of the favourable treatment outcome in this disease and possible complications and lasting effects of surgery, radiotherapy and chemotherapy

    Supraomohyoid neck dissection in the management of cervical lymph node metastases of squamous cell carcinoma of the lower lip

    Background. Supraomohyoid neck dissection (SOHND) is generally considered an adequate staging procedure in selected patients with squamous cell carcinoma (SCC) of the lip and oral cavity, with clinically negative nodes in the neck that are at increased risk for occult metastatic disease. The potential role of SOHND as a therapeutic surgical procedure for cervical metastasis limited to level I is controversial. Methods. A series of 44 patients with clinical cervical lymph node metastases at level I from SCC of the lower lip is reported to evaluate the results of a treatment protocol consisting of therapeutic SOHND on indication followed by radiotherapy. Results. Regional recurrences were observed in four (9%) patients. All recurrences developed within the SOHND dissected area only. Conclusions. A therapeutic SOHND, on indication followed by radiotherapy, can be an oncologically sound and effective procedure in the management of regional lymph node metastases at level I from SCC of the lower lip.

    A review of the most promising biomarkers for early diagnosis and prognosis prediction of tongue squamous cell carcinoma

    Background: There is a great interest in developing biomarkers to enhance early detection and clinical management of tongue squamous cell carcinoma (TSCC). However, the developmental path towards a clinically valid biomarker remains extremely challenging. Ideally, the initial key step in moving a newly discovered biomarker towards clinical implementation is independent replication. Therefore, the focus of this review is on biomarkers that consistently showed clinical relevance in two or more publications. Methods: We searched PubMed database for relevant papers across different TSCC sample sources, i.e., body fluids (saliva, serum/plasma) and tissues. No restriction regarding the date of publication was applied except for immunohistochemistry (IHC); only studies published between 2010 and June 2017 were included. Results: The search strategy identified 1429 abstracts, of which 96 papers, examining 150 biomarkers, were eventually included. Of these papers, 66% were exploratory studies evaluating single or a panel of biomarkers in one publication. Ultimately, based on studies that had undergone validation for their clinical relevance in at least two independent studies, we identified 10 promising candidates, consisting of different types of molecules (IL-6, IL-8, and Prolactin in liquid samples; HIF-1α, SOX2, E-cadherin, vimentin, MALAT1, TP53, and NOTCH1 in tissue biopsies) Conclusions: Although more exploratory research is needed with newer methods to identify biomarkers for TSCC, rigorous validation of biomarkers that have already shown unbiased assessment in at least two publications should be considered a high priority. Further research on these promising biomarkers or their combination in multi-institutional studies, could provide new possibilities to develop a specific panel for early diagnosis, prognosis, and individualized treatments
